Abstract:
A detailed proton second moment and spin-lattice relaxation time investigation of the bilayered compound (C10 21 3 2 4 3 group is involved in a similar reorientation in an asymmetric potential well. Evidence for defect chain motions in this phase has been found, and infomation regarding the potential wells associated with these motions has been extracted from the data. In the high temperature phase, slow chain defect motions and fast fourfold reorientations of chains about their long axes, parallel to the normal to the bilayer, have been observed. © 1993, Walter de Gruyter.
